Flexible PVC Compounds for ELECTRIC WIRE

PVC compound is a non-conductor and because of its chlorine content, it is an excellent fire retardant. For this reason it is the preferred non-conductive material for electrical wire. PVC RYT® compounds are registered by the Underwriters Laboratories (UL), the standards authority in this field in the United States market.

The presence of chlorine in PVC’s molecular structure adds to it fire-retardant and self-extinguishable characteristics. In addition, PVC RYT® compounds are non-conductors of electricity and are resistant to bending and tearing. In addition, they can be formulated to withstand different levels of temperature and exposure to the outdoor elements for decades.

The most important characteristics of PVC for the requirements of this application are as follows:

Electric resistance contributes to the performance of the PVC compound as a primary non-conductor for electrical cables.

Aging in an oven at 60º, 75º, 90º or 105º C indicates the continuous temperature to which the compound can act as a non-conductor without losing its properties.

Exposure to humidity tends to reduce non-conductivity. However PVC compounds are designed to resist humidity in the atmosphere for long periods of time.

Resistance to maximum traction and elongation are physical characteristics of the PVC compound which can be verified before and after the material is under different temperatures, immersed in oil, or outdoors, etc.

Resistance to distortion is evidence of the dimensional stability of the PVC compound when put through continuous compression.

Dielectric resistance measures the non-conductive capacity of the material to resist electric arc.

Resistance to flames and smoke.

These and other properties of PVC RYT® compounds can be optimized to accomplish a suitable performance of each application in the electric industry.
